Crystallization of medium-length 1-alcohols in mesoporous silicon: An x-ray diffraction study

The linear 1-alcohols n{\text{-C}}_{16}{\text{H}}_{33}\text{OH} n{\text{-C}}_{17}{\text{H}}_{35}\text{OH} n{\text{-C}}_{19}{\text{H}}_{39}\text{OH}have been imbibed and solidified in lined up, tubular mesopores of silicon with 10 and 15 nm mean diameters, respectively. X-ray diffraction measurements reveal a set of six discrete orientation states (``domains'') characterized by a perpendicular alignment of the molecules with respect to...
